T0 all'whomit may concern.

Be it known that I, WILLIAM S. TELLS, a citizen of the United States,residing at South Bethlehem, in the county of Lehigh and State ofPennsylvania, have invented certaininew and useful Improvements inWarping Machines, of which the. following is a specification. V Warpingmachines of a well-known type are provided with a going friction member,usually belt-and-pulley driven," which, is shiftable by means of-a foottreadle; and suitable connections into and out of driving contact witha'rigid concentric-drivingband or tread on the reel, the reelyrotatingwhen the contact is established, as by pressing on thetreadle, andcoming toastop when it ceases. Whenever an end breaks and the warper'has to rotate the reel backward to find the broken end he has at presentto do .this by hand, the contact betweenffriction wheel and driving bandon the reel, being of course then disestablished, and as he must alsoemploy his hands in winding the warp paid off by the reel temporarily onhis arm -1n a loose skein or bundlethe operation is 'extremenly tediousand slow and it is a very difiicult matter to find the celerity.

My principal object by this invention is to broken end with providemeans shiftable toward and from the reel and including, with a suitablesup- .port, a 'rotary driven member journaled therein and movabletherewith into and out of driving engagement with the reel, a goingdr1v1ng member also ournaIed 1n sald sup.-

port, and reversible reversinggearing connecting said members,whereby.having properly set the'mechanism for that purpose the reel maybe power-rotated backward as well as forward, thus leaving theattendantfull freedom for winding up the warp on his arm .and watching for thedefect .in the warp when rotating the reel backward; v In the drawings,

Figure 5is a sectional view of the going drivingmember; and I F igure-Gisa plan, partly in sect-ion, of a part of the driven member.

. The reel a is journaled in the frame 6. c is a suitably driven pulleyand d a belt driven thereby. -.e is a treadle fulcrumed in the frame andextending as usual across the machine parallel with the axis of the reeland. in convenient reach of the operators foot. f. is a forked bracketor support fulcrumed in the frame parallel with the reel axis and havingj ournaled therein, also parallel-with said axis, a shaft-g having fixedto its inner ,end, a friction wheel h adapted to bear against the rigidtread orband a on the reel, to drive the same, and having fixed to itsouter end, by the set screw 2', a dished, outwardly concave 1 gear 9'peripherally toothed at the inside. The shaft g, friction 'wheel It andgear together constitute the driven member hereinbefore mentionedlongitudinal movement-thereof is prevented by the bearing portion ofbracket f, which 1 gear and friction wheel-abut.

On the shaft 9 is freely rotative a sleeve 70 which is alined with andabuts the hub gear j, the sleeve being held against movementlongitudinally of the shaft by gear and bearing portions f of thebracket or support The sleeve has a feather Z extending from its outerend partway toward its inner end, and at its inner end it has twodiametric arms m on which are journaled transmission p nions n whlch arehoused in and mesh with the internal teeth of the gear being adapted to'engageina notch g in the arm f'pf the support The sleeve. with its armsand-pinions, and the collar together form the reversible reversinggearing hereinbefore mentioned.

: Journaled on sleeve 70 is a pulley 0" whose periphery receives thebelt d and which has an inward annular flange s so that'the pulley formsa guard around the gear j; the open sideof said gear bears against theface of the ,pulley within the flange so that gear and pulley become ahousing for grease orlubricant, which may be introduced at the pluggedopening t in-the gear. Pulley-whas an inwardly projecting toothedhub-or-pinion. which meshes ---with1,the; pinions: age-and it alsohas-an outwardly projeeti-ngilmb 4) formed with an internal shoulder 11)to abut the end of feather Z and with a notehjmto receive the lug p" ofcollar 1). The pulley is confined by'the feather.-.and gear jagainstmovement longitudinally of the shaft g. Pulley 7* forms theaforementioned going driving member.

'VVith pulley 1" inrotation (beingturned in the direction of thearrow'inFigures '1 by belt cl), it "will'be apparent that 'avl en thecollar vp is by its lugf j)" interlocked with the pulley vthe sleeve 70becomesfast with relation to said pulley .(becz tuse "the collar issplined to the sleeve),-in consequenceof which the pinions nfheldagainst rotation on their own axes, carryfthefdriven member'g, 'h, 7'around .withthe pulleyyso that if the support'be nowfshiftedtobring thefriction wheelv h against: the "reelband a the reel will be rotated inthefdirection of the arrow adjoining it in "Figure "1, or Qforward;-.andthat when thecollar p .is by its lug p interlocked with arm f ofsnpportf the sleeve will be held against rotation,

in consequence of which the rotatingpulley will through the .pinions n,nown'otating on their own axes, rotate'the member ggjh,

j contraryto the direction ,ofrotation first state'dsif the frictionwheel be shifted into contact with the reeli-band a and so.-turn thereel contrary-to-the arrow in Figure 1 Or backward. W'hen the reelisrotate'd' backward it moves at slower speed'than when driven forward, aswill be obvious.

:Having thus fully described my invention,

- -whatI- claiinas new anddesire to secure by Letters Patent is:

5.1. {The combination, with supporting means including a frame and asupport shift- :iable therein, of a rotary element Jto be drivenjournaled in the frame and toward "and fromwhichsaid support isshiftable,
